CHURN SPECIFICATION forming part of Letters Patent No. 337,573, dated March 9, 1886.

' Application filed April 6, 1885. Serial No. 161,344. (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. GERKEN, of Inwood-on-the-Hudson, in the county and State of New York, have invented certain new and useful Improvements in Ohurns, of which the following is a specification.

My invention relates to improvements'in churns; and it has reference to the combination, with the churntub, of a pair of peculiarly-formed holding-clamps, a removable framing formed with extensions adapted to be received into the said clamps, the framing being formed as described, and adapted to support a pair of dashers revolving in opposite directions, and the gearing and driving means for operating the same.

Referring to the drawings, Figure 1 is a front view of my improved device, shown applied to a tub. Fig. 2 is a sectional side view of the same. Fig. 3 is a perspective view of the frame separately. Fig. 4 is a front view, and Fig. 5 is a back view, in perspective, of the clamps separately.

In each of the views similar letters of reference are employed to indicate corresponding parts wherever they occur.

A represents the main framing of my device, which I prefer to form of cast-iron, although other suitable material may be employed. The main framing A is formed of two curved ribs, a a, which are connected together at their upper ends, as shown at b, while intermediately they are connected by transverse ribs 1, 2, and 3, the lower extremity of each of the curved ribsaa being formed with extensions A, adapted to slide into and be held by clamps B, which are adapted to be bolted 0r screwed to the exterior of a tub on opposite sides thereof,'by preference in the same horizontal line. The extensions A are adapted to spring over the bands 1' of the tub B, and are provided with recesses a in their rear, adapted to allow of the said bands 1" being received therein when the frame A is in the proper position.

On the side of the framing A and supported by the-cross-rib 2, which is of curvilinear or other form to admit the free action of a gearwheel, E, hereinafter referred to, is supported a bracket-bearing, B, which is bored out to receive and support a shaft, 0, on one end of which is mounted a driving pulley or wheel, D, while at its opposite end it is provided with a gear-wheel, E, adapted to engage with a pair of gear-wheels, G and H. The gear-wheel G is mounted on a shaft, I, revolving at its upper end in a bearing, K, formed in the cross-rib 1, and is supported by a collar or nut, is, carried by the upper surface of the rib 1. The shaft I also passes through and is supported by the hollow shaft H, upon which the gearwheel H is mounted. The hollow shaft H is supported and revolves in abearing,H formed in or supported by the transverse rib 3.

On the lower end of the'hollow shaft H is mounted a washer, L, to which is connected a pair or series of dashers, which are composed of a cross bar or bars, m, and by preference a pair of vertical strips, m m, extending downward from the cross-bars m. On the lower end of the shaft I is mounted one, or more inner dashers, N, which are also composed of a crossbar or cross-bars, n, and by preference a pair of vertical strips, nn, extending down- .ward from the crossbar n, as shown by dotted lines in Fig. 2. The dashers M and N are driven in opposite directions by means of the gears G and H, to which motion is communicated by the gear-wheel E, carried by the shaft 0, and operated by the pulley or driving-wheel D. In some cases I propose to employ a pair of cross-pieces connecting the blades of the outer dasher, one arranged at the top and the other at the bottom, as shown by dotted lines P in Fig. 2. In this case the lower crosspiece of the dasher is provided with a pivot, p, engaging with a bearing, q, arranged in the bottom of the tub.

The operation of the device is as follows: The shaft 0 being revolved by the driving pulley or wheel D, motion is communicated to the gear-Wheel E, and through it to the gearwhcels G and H in opposite directions. The gear-wheel G, being keyed to the solid inner shaft, I, will revolve the dashers supported thereby in the direction of the arrow 2, while the gear-wheel H, being supported by and affixed to the hollow shaft H, will revolve the outer dashers in the opposite direction, as indicated by the arrow 3 By the peculiar construction of the framing of my churn great simplicity and freedom of B, of the removable metallic gearingframing A, formed with curved ribs a a, transverse 15 ribs 1, 2, and 3, and a bracket-bearing, B, and having extensions A, formed with recesses M, and gearing for operating the dashers, substantially as shown and described.

In witness whereof I have set my hand this 20 3d day of April, 1885.

JOHN H. GERKEN.
